Studies were carried out on a total of 103 children, aged 3-15 years, with birth weight 580-2450 g (mean 1710 g), with myopia of various degree. Relationships between axial length of the eye, birth weight, gestational age, duration of oxygen exposure and the degree of myopia were evaluated. Analyses of vascular and retinal changes in the fundus of the eye typical of regressed retinopathy of prematurity were performed. The values of myopia ranged from 1.5 D to 22.0 D (mean (9.78 D) and axial length from 20.36 to 30.9 mm (mean 25.08). The studies revealed that myopia in retinopathy of prematurity is not associated with the axial elongation of the eyeball. No relationship between the degree of myopia and other examined parameters was found.
